Answer:
Squirrel will take 0.25 hours or 15 minutes
Step-by-step explanation:
Given:
Maximum speed of squirrel = 12 miles/hour
Distance to be covered = 3 miles
To Find:
Time taken to cover the distance = ?
Solution:
We are given the distance and speed of the squirrel and we have to find the time taken by the squirrel
We are given the formula for distance
Distance = speed * time
Now to we have the values
putting in the values
3 = 12 * time
dividing both sides by 12
0.25 hours = time
as one hour = 60 minutes
so
time = 0.25 * 60 minutes
time = 15 minutes
Squirrel will take 0.25 hours or 15 minutes
